Dear FSLers,<br><br>I&#39;m trying to use the peristimulus <span>tsplot</span>
 raw 
data to get task average for some voxels. My scan has 7 repeats, 8 TRs 
tasks followed by 7 TRs rest for each block. I saw the rows showed the 
TRs, but what do the four columns data represent?  <br>
Thanks.<br><br>Best wishes,<br>Emma
